摘要:

在次极小超对称标准模型(NMSSM)中,我们探索了在大型强子对撞机上观测到h1 -> a1 a1 -> 4 μ子信号的可能性.所研究的签名适用于NMSSM参数空间的区域,其中m_a1 <2m_tau,这是以前没有研究过的。在这种情况下,建议的策略,寻找一个四μ子信号与适当的背景抑制将提供一个强大的方法来发现最轻的CP-偶数和CP-奇数NMSSM希格斯玻色子h1和a1。

英文摘要:

We explore the potential of the Large Hadron Collider to observe the h1 -> a1 a1 -> 4 muons signal from the lightest scalar Higgs boson (h1) decaying into the two lightest pseudoscalar Higgs bosons (a1), followed by their decays into four muons in the Next-to-Minimal Supersymmetric Standard Model (NMSSM). The signature under study applies to the region of the NMSSM parameter space in which m_a1 < 2 m_tau, which has not been studied previously. In such a scenario, the suggested strategy of searching for a four-muon signal with the appropriate background suppression would provide a powerful method to discover the lightest CP-even and CP-odd NMSSM Higgs bosons h1 and a1.
